Unravelling the health and economic burden of interstitial lung diseases in adults in Australia.

BACKGROUND: Interstitial lung diseases (ILD) are a heterogenous group of over 200 disorders affecting the pulmonary interstitium. Although there have been advances in knowledge on ILDs in Australia, the characterisation of the health and economic burden of disease remained largely undetermined until recently. OBJECTIVE: The main objective of this review is to provide a synopsis of health and economic burden of ILDs in Australia, based on recently completed research. DISCUSSION: Recent research has demonstrated that idiopathic pulmonary fibrosis (IPF) is the most frequent ILD in Australia. Incidence and prevalence of IPF have demonstrated an increasing trend over the past decades. Mortality has also increased over the past decades, but has shown a slight decreasing trend recently, since the introduction of antifibrotic medication. Health-related quality of life is poor in patients with IPF, and care is estimated to cost approximately AU$299 million per year in Australia. Early diagnosis and referral to tertiary care is crucial for favourable outcomes, and general practitioners are considerably important to this as the first interface to identify patients at risk and detect early symptoms of ILDs.

Novel Therapeutic Approaches in Connective Tissue Disease-Associated Interstitial Lung Disease.

Connective tissue diseases (CTD) comprise a group of autoimmune diseases that can affect multiple organs in the body including the lungs. The most common form of pulmonary involvement is interstitial lung disease (ILD). CTD-associated ILD (CTD-ILD) can take one of several courses including nonprogressive, chronically progressive, or rapidly progressive. Chronically and rapidly progressive patterns are associated with increased mortality. Limited randomized controlled trial data are available for treatment of CTD-ILD, with most data coming from systemic sclerosis-related ILD. The current first-line treatment for all CTD-ILD is immunosuppression with consideration of antifibrotics, stem cell transplant, and lung transplant in progressive disease. In this article, we review data for ILD treatment options in systemic sclerosis, rheumatoid arthritis, myositis, and primary Sjögren's syndrome-related ILDs.

Interstitial Lung Disease: A Review.

Importance: Interstitial lung disease (ILD) consists of a group of pulmonary disorders characterized by inflammation and/or fibrosis of the lung parenchyma associated with progressive dyspnea that frequently results in end-stage respiratory failure. In the US, ILD affects approximately 650 000 people and causes approximately 25 000 to 30 000 deaths per year. Observations: The most common forms of ILD are idiopathic pulmonary fibrosis (IPF), which accounts for approximately one-third of all cases of ILD, hypersensitivity pneumonitis, accounting for 15% of ILD cases, and connective tissue disease (CTD), accounting for 25% of ILD cases. ILD typically presents with dyspnea on exertion. Approximately 30% of patients with ILD report cough. Thoracic computed tomography is approximately 91% sensitive and 71% specific for diagnosing subtypes of ILDs such as IPF. Physiologic assessment provides important prognostic information. A 5% decline in forced vital capacity (FVC) over 12 months is associated with an approximately 2-fold increase in mortality compared with no change in FVC. Antifibrotic therapy with nintedanib or pirfenidone slows annual FVC decline by approximately 44% to 57% in individuals with IPF, scleroderma associated ILD, and in those with progressive pulmonary fibrosis of any cause. For connective tissue disease-associated ILD, immunomodulatory therapy, such as tocilizumab, rituximab, and mycophenolate mofetil, may slow decline or even improve FVC at 12-month follow-up. Structured exercise therapy reduces symptoms and improves 6-minute walk test distance in individuals with dyspnea. Oxygen reduces symptoms and improves quality of life in individuals with ILD who desaturate below 88% on a 6-minute walk test. Lung transplant may improve symptoms and resolve respiratory failure in patients with end-stage ILD. After lung transplant, patients with ILD have a median survival of 5.2 to 6.7 years compared with a median survival of less than 2 years in patients with advanced ILD who do not undergo lung transplant. Up to 85% of individuals with end-stage fibrotic ILD develop pulmonary hypertension. In these patients, treatment with inhaled treprostinil improves walking distance and respiratory symptoms. Conclusions and Relevance: Interstitial lung disease typically presents with dyspnea on exertion and can progress to respiratory failure. First-line therapy includes nintedanib or pirfenidone for IPF and mycophenolate mofetil for ILD due to connective tissue disease. Lung transplant should be considered for patients with advanced ILD. In patients with ILD, exercise training improves 6-minute walk test distance and quality of life.

Pleuroparenchymal fibroelastosis as a late complication of childhood cancer therapy: A case series.

Pleuroparenchymal fibroelastosis (PPFE) is a rare interstitial pneumonia with distinct clinicopathologic features. It has been associated with exposure to hematopoietic stem cell transplantation (HSCT) and classical alkylating agents. Here, we highlight PPFE as a late complication of childhood cancer therapy by describing the cases of four survivors of childhood cancer with a diagnosis of treatment-related PPFE. All patients received high-dose alkylating agents. PPFE should be considered in the differential diagnosis of restrictive lung disease in patients with history of exposure to alkylating agents or HSCT. Development of PPFE-specific, noninvasive diagnostic tools and disease-modifying therapies will clinically benefit these patients.

Disease trajectories in interstitial lung diseases - data from the EXCITING-ILD registry.

BACKGROUND: Interstitial lung diseases (ILD) comprise a heterogeneous group of mainly chronic lung diseases with different disease trajectories. Progression (PF-ILD) occurs in up to 50% of patients and is associated with increased mortality. METHODS: The EXCITING-ILD (Exploring Clinical and Epidemiological Characteristics of Interstitial Lung Diseases) registry was analysed for disease trajectories in different ILD. The course of disease was classified as significant (absolute forced vital capacity FVC decline > 10%) or moderate progression (FVC decline 5-10%), stable disease (FVC decline or increase < 5%) or improvement (FVC increase ≥ 5%) during time in registry. A second definition for PF-ILD included absolute decline in FVC % predicted ≥ 10% within 24 months or ≥ 1 respiratory-related hospitalisation. Risk factors for progression were determined by Cox proportional-hazard models and by logistic regression with forward selection. Kaplan-Meier curves were utilised to estimate survival time and time to progression. RESULTS: Within the EXCITING-ILD registry 28.5% of the patients died (n = 171), mainly due to ILD (n = 71, 41.5%). Median survival time from date of diagnosis on was 15.5 years (range 0.1 to 34.4 years). From 601 included patients, progression was detected in 50.6% of the patients (n = 304) with shortest median time to progression in idiopathic NSIP (iNSIP; median 14.6 months) and idiopathic pulmonary fibrosis (IPF; median 18.9 months). Reasons for the determination as PF-ILD were mainly deterioration in lung function (PFT; 57.8%) and respiratory hospitalisations (40.6%). In multivariate analyses reduced baseline FVC together with age were significant predictors for progression (OR = 1.00, p < 0.001). Higher GAP indices were a significant risk factor for a shorter survival time (GAP stage III vs. I HR = 9.06, p < 0.001). A significant shorter survival time was found in IPF compared to sarcoidosis (HR = 0.04, p < 0.001), CTD-ILD (HR = 0.33, p < 0.001), and HP (HR = 0.30, p < 0.001). Patients with at least one reported ILD exacerbation as a reason for hospitalisation had a median survival time of 7.3 years (range 0.1 to 34.4 years) compared to 19.6 years (range 0.3 to 19.6 years) in patients without exacerbations (HR = 0.39, p < 0.001). CONCLUSION: Disease progression is common in all ILD and associated with increased mortality. Most important risk factors for progression are impaired baseline forced vital capacity and higher age, as well as acute exacerbations and respiratory hospitalisations for mortality. Early detection of progression remains challenging, further clinical criteria in addition to PFT might be helpful.

[A CASE OF CLINICALLY AMYOPATHIC DERMAMYOSITIS WITH INTERSTITIAL LUNG DISEASE SHOWING TWO DETERIORATIONS IN 4 YEARS].

We report the case of a 45-year-old man who was diagnosed with clinically amyopathic dermamyositis (CADM) and interstitial lung disease (ILD) after presenting with skin lesions typical of CADM and testing positive for anti-Melanoma Diferentiation-Associated gene 5 (anti-MDA5) anti-bodies. He was treated with a regimen including steroid pulse therapy, intravenous cyclophosphamide (IVCY), and calcineurin Inhibitor drug, which initially improved his ILD. However, three months post-treatment, the first deterioration of his conditions occurred, necessitating further administration of steroid pulse therapy and IVCY. After eight cycles of IVCY therapy, the serum levels of KL-6 and anti-MDA5 antibodies decreased, and reaching their lowest values. Nevertheless, two years and six months after the first observed deterioration, the second deterioration of his conditions occurred, leading to acute respiratory failure, treated again with steroid pulse therapy and IVCY. This treatment did not result in improvement of respiratory failure, therefore plasma exchange was attempted, which demonstrated a beneficial effect on the ILD for a short time. This case suggests that IVCY and plasma exchange might be effective therapeutic options for CADM with ILD.

Effectiveness and safety of plasma exchange for anti-MDA5 antibody-positive clinically amyopathic dermatomyositis with rapidly progressive interstitial lung disease refractory to intensive immune suppression therapy: A case series.

INTRODUCTION: Clinically amyopathic dermatomyositis (CADM) with anti-melanoma differentiation-associated gene 5 (MDA5) antibody (Ab) with rapidly progressive interstitial lung disease (RP-ILD) is often refractory for intensive immunosuppression. In this study, we verified the effectiveness and safety of plasma exchange (PEx) for this lethal disease. METHODS: We retrospectively examined the clinical course and adverse effect (AE) of 12 patients with anti-MDA5 Ab-positive CADM between January 2017 and December 2021 in our hospital. RESULTS: Five out of six patients treated with simple PEx using fresh frozen plasma or 5% albumin survived with or without home oxygen therapy. Multiple PEx (15-20 times) were required to achieve satisfactory improvement as well as remission of CADM. The AEs caused by PEx were resolved using conventional methods. CONCLUSION: PEx might be a promising option for controlling the disease activity of anti-MDA5 Ab-positive CADM with severe RP-ILD and may contribute to better survival.

Nurse and Social Worker Palliative Telecare Team and Quality of Life in Patients With COPD, Heart Failure, or Interstitial Lung Disease: The ADAPT Randomized Clinical Trial.

Importance: Many patients with chronic obstructive pulmonary disease (COPD), heart failure (HF), and interstitial lung disease (ILD) endure poor quality of life despite conventional therapy. Palliative care approaches may benefit this population prior to end of life. Objective: Determine the effect of a nurse and social worker palliative telecare team on quality of life in outpatients with COPD, HF, or ILD compared with usual care. Design, Setting, and Participants: Single-blind, 2-group, multisite randomized clinical trial with accrual between October 27, 2016, and April 2, 2020, in 2 Veterans Administration health care systems (Colorado and Washington), and including community-based outpatient clinics. Outpatients with COPD, HF, or ILD at high risk of hospitalization or death who reported poor quality of life participated. Intervention: The intervention involved 6 phone calls with a nurse to help with symptom management and 6 phone calls with a social worker to provide psychosocial care. The nurse and social worker met weekly with a study primary care and palliative care physician and as needed, a pulmonologist, and cardiologist. Usual care included an educational handout developed for the study that outlined self-care for COPD, ILD, or HF. Patients in both groups received care at the discretion of their clinicians, which could include care from nurses and social workers, and specialists in cardiology, pulmonology, palliative care, and mental health. Main Outcomes and Measures: The primary outcome was difference in change in quality of life from baseline to 6 months between the intervention and usual care groups (FACT-G score range, 0-100, with higher scores indicating better quality of life, clinically meaningful change ≥4 points). Secondary quality-of-life outcomes at 6 months included disease-specific health status (Clinical COPD Questionnaire; Kansas City Cardiomyopathy Questionnaire-12), depression (Patient Health Questionnaire-8) and anxiety (Generalized Anxiety Disorder-7) symptoms. Results: Among 306 randomized patients (mean [SD] age, 68.9 [7.7] years; 276 male [90.2%], 30 female [9.8%]; 245 White [80.1%]), 177 (57.8%) had COPD, 67 (21.9%) HF, 49 (16%) both COPD and HF, and 13 (4.2%) ILD. Baseline FACT-G scores were similar (intervention, 52.9; usual care, 52.7). FACT-G completion was 76% (intervention, 117 of 154; usual care, 116 of 152) at 6 months for both groups. Mean (SD) length of intervention was 115.1 (33.4) days and included a mean of 10.4 (3.3) intervention calls per patient. In the intervention group, 112 of 154 (73%) patients received the intervention as randomized. At 6 months, mean FACT-G score improved 6.0 points in the intervention group and 1.4 points in the usual care group (difference, 4.6 points [95% CI, 1.8-7.4]; P = .001; standardized mean difference, 0.41). The intervention also improved COPD health status (standardized mean difference, 0.44; P = .04), HF health status (standardized mean difference, 0.41; P = .01), depression (standardized mean difference, -0.50; P < .001), and anxiety (standardized mean difference, -0.51; P < .001) at 6 months. Conclusions and Relevance: For adults with COPD, HF, or ILD who were at high risk of death and had poor quality of life, a nurse and social worker palliative telecare team produced clinically meaningful improvements in quality of life at 6 months compared with usual care. Trial Registration: ClinicalTrials.gov Identifier: NCT02713347.

Hospitalisation patterns in interstitial lung diseases: data from the EXCITING-ILD registry.

BACKGROUND: Interstitial lung diseases (ILD) comprise a heterogeneous group of mainly chronic lung diseases with more than 200 entities and relevant differences in disease course and prognosis. Little data is available on hospitalisation patterns in ILD. METHODS: The EXCITING-ILD (Exploring Clinical and Epidemiological Characteristics of Interstitial Lung Diseases) registry was analysed for hospitalisations. Reasons for hospitalisation were classified as all cause, ILD-related and respiratory hospitalisations, and patients were analysed for frequency of hospitalisations, time to first non-elective hospitalisation, mortality and progression-free survival. Additionally, the risk for hospitalisation according to GAP index and ILD subtype was calculated by Cox proportional-hazard models as well as influencing factors on prediction of hospitalisation by logistic regression with forward selection. RESULTS: In total, 601 patients were included. 1210 hospitalisations were recorded during the 6 months prior to registry inclusion until the last study visit. 800 (66.1%) were ILD-related, 59.3% of admissions were registered in the first year after inclusion. Mortality was associated with all cause, ILD-related and respiratory-related hospitalisation. Risk factors for hospitalisation were advanced disease (GAP Index stages II and III) and CTD (connective tissue disease)-ILDs. All cause hospitalisations were associated with pulmonary hypertension (OR 2.53, p = 0.005). ILD-related hospitalisations were associated with unclassifiable ILD and concomitant emphysema (OR = 2.133, p = 0.001) as well as with other granulomatous ILDs and a positive smoking status (OR = 3.082, p = 0.005). CONCLUSION: Our results represent a crucial contribution in understanding predisposing factors for hospitalisation in ILD and its major impact on mortality. Further studies to characterize the most vulnerable patient group as well as approaches to prevent hospitalisations are warranted.

Allogeneic Hematopoietic Cell Transplantation Ameliorated Asymptomatic Granulomatous and Lymphocytic Interstitial Lung Disease in a Patient With XIAP Deficiency.

X-linked inhibitor of apoptosis protein (XIAP) deficiency is an inborn error of immunity (IEI). Allogeneic hematopoietic cell transplantation (HCT) is currently the only curative therapy available for XIAP deficiency. Granulomatous and lymphocytic interstitial lung disease (GLILD) is a common immune-related lung complication of IEIs. We present a 6-year-old boy with XIAP deficiency and GLILD. Computed tomography showed lung nodes but no symptoms. Before HCT, GLILD was not managed with immunosuppressive therapy, because he was asymptomatic. The HCT procedure was subsequently performed. The post-HCT course was uneventful; follow-up computed tomography on day 46 showed nodules had disappeared. HCT could potentially ameliorate GLILD like other inflammatory processes associated with the underlying IEIs.

[Update in interstitial lung disease 2023].

The notable advances in interstitial lung disease (ILD) published in Chinese and international authoritative journals from November 2022 to October 2023 were systematically reviewed in our annual review. The year 2023 brought significant advances about mechanism, diagnosis and treatment of idiopathic pulmonary fibrosis, connective tissue diseases associated ILD, sarcoidosis, progressive pulmonary fibrosis and rare ILDs. The related global and/or Chinese commentaries and guidelines were also reviewed in our paper. We also highlighted the important findings of epidemiologic and health economic data on idiopathic pulmonary fibrosis and sarcoidosis.

Early Initiation of Plasma Exchange Therapy for Anti-MDA5+Dermatomyositis with Refractory Rapidly Progressive Interstitial Lung Disease.

Objectives Dermatomyositis (DM) is often associated with fatal anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive rapidly progressive interstitial lung disease (RP-ILD). RP-ILD often fails to respond to intensive treatment and has a poor prognosis. We examined the effectiveness of early plasma exchange therapy plus intensive treatment with high-dose corticosteroids and multiple immunosuppressants. Methods Autoantibodies were identified by an immunoprecipitation assay and enzyme-linked immunosorbent assay. All clinical and immunological data were collected retrospectively from medical charts. We divided patients into two groups based on treatment regimen: intensive immunosuppressive therapy alone as initial treatment (IS group) and early initiation of plasma exchange (PE) plus intensive immunosuppressive therapy (ePE group). Early PE therapy was designated if PE therapy was initiated within two weeks of starting treatment. Comparisons of the treatment response and prognosis between groups were performed. Patients Anti-MDA5-positive DM with RP-ILD was screened. Results Forty-four RP-ILD and DM patients had anti-MDA5 antibodies. Four patients were excluded because they died before receiving sufficient combined immunosuppressive therapy or before the evaluation of the immunosuppressive treatment effectiveness (IS, n=31; ePE, n=9). All 9 patients in the ePE group had improved respiratory symptoms and were alive, whereas 12 of 31 patients in the IS group died (100 vs. 61%, p=0.037). Of the 8 patients who had 2 values for a poor prognosis, indicating the highest risk for death using the MCK model, 3 of 3 patients in the ePE group and 2 of 5 in the IS group were alive (100 vs. 40%, p=0.20). Conclusion The early initiation of ePE therapy plus intensive immunosuppressive therapy was effective for patients with DM and refractory RP-ILD.

Childhood interstitial lung disease in Turkey: first data from the national registry.

The childhood interstitial lung diseases (chILD) Turkey registry (chILD-TR) was established in November 2021 to increase awareness of disease, and in collaboration with the centers to improve the diagnostic and treatment standards. Here, the first results of the chILD registry system were presented. In this prospective cohort study, data were collected using a data-entry software system. The demographic characteristics, clinical, laboratory, radiologic findings, diagnoses, and treatment characteristics of the patients were evaluated. Clinical characteristics were compared between two main chILD groups ((A) diffuse parenchymal lung diseases (DPLD) disorders manifesting primarily in infancy [group1] and (B) DPLD disorders occurring at all ages [group 2]). There were 416 patients registered from 19 centers. Forty-six patients were excluded due to missing information. The median age of diagnosis of the patients was 6.05 (1.3-11.6) years. Across the study population (n = 370), 81 (21.8%) were in group 1, and 289 (78.1%) were in group 2. The median weight z-score was significantly lower in group 1 (- 2.0 [- 3.36 to - 0.81]) than in group 2 (- 0.80 [- 1.7 to 0.20]) (p < 0.001). When we compared the groups according to chest CT findings, ground-glass opacities were significantly more common in group 1, and nodular opacities, bronchiectasis, mosaic perfusion, and mediastinal lymphadenopathy were significantly more common in group 2. Out of the overall study population, 67.8% were undergoing some form of treatment. The use of oral steroids was significantly higher in group 2 than in group 1 (40.6% vs. 23.3%, respectively; p = 0.040).   Conclusion: This study showed that national registry allowed to obtain information about the frequency, types, and treatment methods of chILD in Turkey and helped to see the difficulties in the diagnosis and management of these patients. What is Known: • Childhood interstitial lung diseases comprise many diverse entities which are challenging to diagnose and manage. What is New: • This study showed that national registry allowed to obtain information about the frequency, types and treatment methods of chILD in Turkey and helped to see the difficulties in the diagnosis and management of these patients. Also, our findings reveal that nutrition should be considered in all patients with chILD, especially in A-DPLD disorders manifesting primarily in infancy.

Incidence of interstitial lung disease in patients with breast cancer: a nationwide database study in Japan.

Aim: This study estimated the incidence of moderate-to-severe drug-induced interstitial lung disease (ILD) among patients with breast cancer in Japan. Methods: We analyzed a large nationwide database of patients with breast cancer treated with anticancer therapies between 2009 and 2022. ILD was identified using diagnostic codes and treatment records. Results: Of the 81,601 patients, 1042 developed ILD requiring corticosteroids, corresponding to an incidence rate of 1.41 per 100 person-years. The incidence varied across years and treatment regimens. Most ILD incidents occurred within the initial 90-day period post-anticancer therapy initiation. Conclusion: Increase in ILD cases and potential risk variations among treatments underline the importance of continued monitoring, especially during treatment onset, and ILD management in patients with breast cancer undergoing therapy.

This article investigates how often a lung condition known as interstitial lung disease (ILD) occurs in patients treated for breast cancer in Japan. ILD can cause inflammation and damage to the lungs and can be a side effect of some cancer treatments. The study looked at over 81,000 patients with breast cancer from 2009 to 2022. A total of 1042 patients developed ILD that required treatment with steroids to reduce inflammation. This number suggests that ILD occurred in 1.41 out of every 100 patients treated each year. The study noted that the chances of developing ILD varied over the years and depended on the type of cancer treatment. The findings showed that ILD is a risk factor for patients undergoing breast cancer treatment, and the risk can change depending on the treatment they receive. This highlights the importance of doctors keeping a close eye on their patients, especially early in the treatment process, to identify and manage any signs of ILD. Careful monitoring can help improve the health and treatment outcomes of patients with breast cancer. The study also points to the need for more research to understand why ILD occurs and how to prevent or treat it.

Variation in information needs of patients with interstitial lung disease and their family caregivers according to long-term oxygen therapy: a descriptive study.

BACKGROUND: The information needs of patients and their families regarding interstitial lung disease (ILD) have yet to be studied in detail, and few reports have examined the differences in information needs according to patient status. This study aimed to determine whether there are differences in information needs between outpatients with ILD and their family caregivers and whether these differences depend on long-term oxygen therapy use. METHODS: Patients with fibrotic ILDs and their families who visited Kyoto University Hospital between February 2020 and March 2022 were recruited for this descriptive study. Fibrotic ILDs included idiopathic pulmonary fibrosis (IPF), other idiopathic interstitial pneumonias (IIPs) than IPF, connective tissue disease-associated ILD (CTD-ILD), and fibrotic hypersensitivity pneumonia. Data were obtained from electronic patient records and questionnaires. Descriptive data analyses were performed. RESULTS: Sixty-five patients and their family caregivers were analyzed. Twenty-seven (41.5%) patients had IIPs (IPF 9 and other IIPs 18), 34 (52.3%) had CTD-ILD, and 4 (6.2%) had fibrotic hypersensitivity pneumonia. The most common relationship between the patient and their family was a spouse (67.7%), with 80% living together. The primary information needs among patients and their family caregivers were common up to the third rank but differed from the rest. Patients were interested in "when and where to contact health care providers" and "end-of-life care and advanced directives," while family caregivers were interested in "diet and nutrition" and "care and support at home." Patients with long-term oxygen therapy had higher needs for "end-of-life care and advanced directives" and "how to manage breathlessness, cough, and fatigue," while the needs for "drugs for ILD" and "acute exacerbation of ILD" were relatively low. Family caregivers were interested in "diet and nutrition" in the long-term oxygen therapy group and "acute exacerbation of ILD" in the no long-term oxygen therapy group. CONCLUSIONS: This study found that the information needs of patients and their family caregivers were not the same and that the aspect of information needs differed by long-term oxygen therapy status. Healthcare providers should consider the position of the recipient of information, the appropriate time based on the patient's condition, and the necessary information.

Mechanisms and management of cough in interstitial lung disease.

INTRODUCTION: Many patients with interstitial lung diseases (ILDs), especially fibrotic ILDs, experience chronic cough. It negatively impacts both physical and psychological well-being. Effective treatment options are limited. AREAS COVERED: The pathophysiology of chronic cough in IPF is complex and involves multiple mechanisms, including mechanical distortion of airways, parenchyma, and nerve fibers. The pathophysiology of cough in other fibrosing ILDs is poorly understood and involves various pathways. The purpose of this review is to highlight mechanisms of chronic cough and to present therapeutic evidence for its management in the most commonly occurring diffuse fibrosing lung diseases including idiopathic pulmonary fibrosis (IPF), connective tissue disease-related interstitial lung disease (CTD-ILD), sarcoidosis-related ILD (Sc-ILD), chronic hypersensitivity pneumonitis-related ILD (CHP-ILD), and post-COVID-19-related interstitial lung disease (PC-ILD). EXPERT OPINION: This review guides the management of chronic cough in fibrosing ILDs. In this era of precision medicine, chronic cough management should be individualized in each interstitial lung disease.

Abordaje paliativo en enfermedades respiratorias avanzadas / Palliative Approach in Advanced Respiratory Diseases

Las enfermedades respiratorias crónicas avanzadas son prevalentes y producen deterioro de la calidad de vida, en particular la enfermedad pulmonar obstructiva crónica (EPOC), las enfermedades pulmonares intersticiales difusas (EPID) y las enfermedades neuromusculares progresivas con compromiso diafragmático (ENM). Quienes las padecen presentan síntomas persistentes que no son siempre adecuada-mente controlados por los tratamientos recomendados por las guías clínicas de mane-jo. El tratamiento paliativo de los síntomas persistentes es un punto relevante y suelen presentarse barreras para su implementación.Este artículo ofrece una revisión narrativa sobre una perspectiva latinoamericana acerca del rol de los cuidados paliativos en enfermedades respiratorias avanzadas.

Advanced chronic respiratory diseases are prevalent and cause deterioration in qual-ity of life, particularly chronic obstructive pulmonary disease (COPD), diffuse intersti-tial lung diseases (ILD) and progressive neuromuscular diseases with diaphragmatic involvement (NMD). Those who suffer from them usually present persistent symptoms that are not always adequately controlled by the treatments recommended by the clinical management guidelines. Palliative treatment of persistent symptoms is a relevant point, but the pal-liative approach usually presents barriers to its implementation.This article offers a narrative review over Latin American perspective on the role of pal-liative care in advanced respiratory diseases.

[Chinese expert consensus on multidisciplinary discussion of interstitial lung disease].

Interstitial lung disease (ILD) is a group of heterogeneous diseases characterized by interstitial lung inflammation and fibrosis. Its causes are diverse, symptoms can be non-specific, and the associated imaging and pathologic patterns can vary widely. The diagnosis and management of these conditions often require input from multiple medical disciplines. Over the past few decades, the importance of multidisciplinary discussion (MDD) in the management of ILD has grown internationally, and MDD has gradually become a part of the gold standard for ILD diagnosis and an essential reference for disease management. Recognizing this, the Chinese Medical Association-Chinese Thoracic Society and the Chinese Association of Chest Physicians have collaborated with experts to standardize the ILD-MDD process in China.Key recommendations:1. Formation of teams: ILD centers should establish multidisciplinary teams (MDT) and integrate MDD into the ILD patient care process. (strong recommendation)2. Patient preparation: Prior to ILD-MDD, patients should undergo as thorough an ILD assessment as possible, including medical history, diagnostic tests, and functional evaluations. (strong recommendation)3. MDD frequency & logistics:(1) The frequency, duration and number of cases to be discussed in ILD-MDD should be based on the clinical needs of each center, but should be held at least monthly. (2) Consistent timing and location of ILD-MDD is recommended to improve attendance. (medium recommendation)4. Team composition: The MDT should include experts from a range of disciplines with experience of ILD. These should include specialists in Pulmonary and Critical Care Medicine, Radiology, and Pathology. Where appropriate, experts in Rheumatology, Hematology, Thoracic Surgery, and Respiratory Care and Rehabilitation should also be involved. (strong recommendation)5. Case presentation & goals:(1) The physician in charge should present clinical information, preferably using standardized slides. Real-time imaging and pathology data are encouraged. (2) The primary goals of ILD-MDD discussions should be disease diagnosis and management. (strong recommendation)6. Operational leadership: Assign a dedicated professional to manage the ILD-MDD operations and maintain the information discussed. (strong recommendation)7. Specific conditions:(1) Suspected idiopathic pulmonary fibrosis should be diagnosed by a standardized MDD process. (2) Suspected idiopathic interstitial pneumonia (IIP) should be classified by MDD. If IIP is indicated by imaging or pathology, prioritize identifying potential underlying causes such as connective tissue diseases (CTDs), certain medications, or aspiration.(3) Suspected hypersensitivity pneumonitis should also be diagnosed by MDD. (4) If an ILD patient shows signs suggestive of CTDs, the diagnosis should be made by ILD-MDD with the involvement of rheumatologists. (strong recommendation)8. Unclassifiable ILD: For ILD patients who cannot be clearly classified, create a tailored management plan based on the patient's specific disease features. (strong recommendation)9. Progressive pulmonary fibrosis: Use ILD-MDD to determine whether an ILD patient meets the criteria for progressive pulmonary fibrosis and to discuss a personalized care plan. (strong recommendation).
